Associations between hope and trajectories of critical consciousness among U.S. youth of color.

We examined associations between hope as an internal asset that supports positive youth development, and growth trajectories of three critical consciousness components. Using five waves of data collected over the course of high school (N = 618), we modeled growth trajectories of awareness of inequity (critical reflection), a sense of agency about taking sociopolitical action (critical agency), and behaviors targeting systems of oppression (critical action). Hope was highest among those with high trajectories of critical agency and critical action.

The Neural Representation of a Repeated Standard Stimulus in Dyslexia.

The neural representation of a repeated stimulus is the standard against which a deviant stimulus is measured in the brain, giving rise to the well-known mismatch response. It has been suggested that individuals with dyslexia have poor implicit memory for recently repeated stimuli, such as the train of standards in an oddball paradigm. Here, we examined how the neural representation of a standard emerges over repetitions, asking whether there is less sensitivity to repetition and/or less accrual of "standardness" over successive repetitions in dyslexia.

Neural Decoding Reveals Concurrent Phonemic and Subphonemic Representations of Speech Across Tasks.

Robust and efficient speech perception relies on the interpretation of acoustically variable phoneme realizations, yet prior neuroimaging studies are inconclusive regarding the degree to which subphonemic detail is maintained over time as categorical representations arise. It is also unknown whether this depends on the demands of the listening task. We addressed these questions by using neural decoding to quantify the (dis)similarity of brain response patterns evoked during two different tasks.
